Which expression, when simplified, is equal to 7p? a) 9p – 2pq – 7p – 5p + 2pq b) 9p – 2pq – 7p + 5p – 2pq c) 9p + 2pq – 7p + 5p – 2pq d) 9p + 2pq + 7p + 5p – 2pq e) 9p + 2pq – 7p + 5p + 2pq

C

Step-by-step explanation:

2pq - 2pq is zero. B and E have no zero pq coefficient.

p(9-7+5) = 7p

glide reflection.

its mainly because the pattern will be infinite and will never end. it will look like a gilder or like a filpbook when set to motion.

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
